Abstract
The ban on the use of Antibiotic Growth Promoter (AGP) in feed makes farmers doubt the efficiency of feed conversion by poultry, especially broilers. This study aims to determine the effectiveness of the addition of natural feed additives on the production performance and quality of broilers. The sample used in this study was DOC (Day Old Chicken) Cobb strain with the trademark CP 707 as many as 75 heads. The method used was experimental designed using a completely randomized design with three treatments and five replicates used five broilers per replicate. The treatments were T0 = basal feed, T1 = basal feed with 0.5% natural feed additive, and T2 = basal feed with 1.0% natural feed additive. The variables used in this study were villous characteristics including villous length, number of villi, and depth of villous crypts. Data were analyzed with ANOVA and continued with Duncan^s multiple range test. The results showed that the test of villi characteristics using natural feed additive combination of probiotics-phytobiotics-acidifier microencapsulation gave a significantly different effect (P>0.05) on the number and depth of villi crypts, but gave a significantly different effect (P>0.01) on villi length. The use of natural feed additive combination of probiotics-phytobiotics-acidifiers gives effective results on the characteristics of intestinal villi in the ileum section giving good results at the level of use of 1.0% and can be used to replace antibiotics.
